Table 1-2: Additional documentation and resources 4 Topic Document Sensor Sensor documentation Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Before you begin Table 1-2: Additional documentation and resources (continued) Topic Document Transmitter installation Micro Motion Model 1700 and Model 2700 Transmitters: Installation Manual Hazardous area installation See the approval documentation shipped with the transmitter, or download the appropriate documentation from the Micro Motion web site at www.micromotion.com. All documentation resources are available on the Micro Motion web site at www.micromotion.com or on the Micro Motion user documentation CD. Configuration and Use Manual 5 Before you begin 6 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Quick start 2 Quick start Topics covered in this chapter: • • • • • • 2.1 Power up the transmitter Check flowmeter status Make a startup connection to the transmitter Characterize the flowmeter (if required) Verify mass flow measurement Verify the zero Power up the transmitter The transmitter must be powered up for all configuration and commissioning tasks, or for process measurement. 1. Ensure that all transmitter and sensor covers and seals are closed. CAUTION! To prevent ignition of flammable or combustible atmospheres, ensure that all covers and seals are tightly closed. For hazardous area installations, applying power while housing covers are removed or loose can cause an explosion. 2. Turn on the electrical power at the power supply. The transmitter will automatically perform diagnostic routines. During this period, Alarm 009 is active. The diagnostic routines should complete in approximately 30 seconds. For transmitters with a display, the status LED will turn green and begin to flash when the startup diagnostics are complete. If the status LED exhibits different behavior, an alarm condition is present. Postrequisites Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power is been off long enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately 10 minutes before relying on process measurements. During this warm-up period, you may observe minor measurement instability or inaccuracy. 2.2 Check flowmeter status Check the flowmeter for any error conditions that require user action or that affect measurement accuracy. Configuration and Use Manual 7 Quick start 1. Wait approximately 10 seconds for the power-up sequence to complete. Immediately after power-up, the transmitter runs through diagnostic routines and checks for error conditions. During the power-up sequence, Alarm A009 is active. This alarm should clear automatically when the power-up sequence is complete. 2. Check the status LED on the transmitter. Table 2-1: Transmitter status reported by status LED LED state Description Recommendation Green No alarms are active. Continue with configuration or process measurement. Flashing green(1) No alarms are active. One or more previously active alarms have not been acknowledged. Continue with configuration or process measurement. If you choose, you can acknowledge the alarms. Yellow One or more low-severity alarms are active, and have been acknowledged. A low-severity alarm condition does not affect measurement accuracy or output behavior. You can continue with configuration or process measurement. If you choose, you can identify and resolve the alarm condition. Flashing yellow(2) One or more low-severity alarms are active and have not been acknowledged. A low-severity alarm condition does not affect measurement accuracy or output behavior. You can continue with configuration or process measurement. If you choose, you can identify and resolve the alarm condition. You may also acknowledge the alarm. Red One or more high-severity alarms are active, and have been acknowledged. A high-severity alarm condition affects measurement accuracy and output behavior. Resolve the alarm condition before continuing. Flashing red(3) One or more high-severity alarms are active and have not been acknowledged. A high-severity alarm condition affects measurement accuracy and output behavior. Resolve the alarm condition before continuing. You may also acknowledge the alarm. Postrequisites For information on viewing the list of active alarms, see Section 9.4. For information on individual alarms and suggested resolutions, see Section 12.2. (1) If Status LED Blinking is disabled, the LED will show solid green rather than flashing. (2) If Status LED Blinking is disabled, the LED will show solid yellow rather than flashing. (3) If Status LED Blinking is disabled, the LED will show solid red rather than flashing. 8 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Quick start 2.3 Make a startup connection to the transmitter For all configuration tools except the display, you must have an active connection to the transmitter to configure the transmitter. Identify the connection type to use, and follow the instructions for that connection type in the appropriate appendix. 2.4 Communications tool Connection type to use Instructions ProLink II Service port Appendix B ProLink III Service port Appendix C Field Communicator HART Appendix D Characterize the flowmeter (if required) Display Not available ProLink II • ProLink > Configuration > Device > Sensor Type • ProLink > Configuration > Flow • ProLink > Configuration > Density • ProLink > Configuration > T Series ProLink III Device Tools > Calibration Data Field Communicator Configure > Manual Setup > Characterize Overview Characterizing the flowmeter adjusts your transmitter to match the unique traits of the sensor it is paired with. The characterization parameters (also called calibration parameters) describe the sensor’s sensitivity to flow, density, and temperature. Depending on your sensor type, different parameters are required. Values for your sensor are provided by Micro Motion on the sensor tag or the calibration certificate. Tip If your flowmeter was ordered as a unit, it has already been characterized at the factory. However, you should still verify the characterization parameters. Procedure 1. Specify Sensor Type. • Straight-tube (T-Series) • Curved-tube (all sensors except T-Series) 2. Set the flow characterization parameters. Be sure to include all decimal points. Configuration and Use Manual 9 Quick start • For straight-tube sensors, set FCF (Flow Cal or Flow Calibration Factor), FTG, and FFQ. • For curved-tube sensors, set Flow Cal (Flow Calibration Factor). 3. Set the density characterization parameters. • For straight-tube sensors, set D1, D2, DT, DTG, K1, K2, FD, DFQ1, and DFQ2. • For curved-tube sensors, set D1, D2, TC, K1, K2, and FD. (TC is sometimes shown as DT.) 2.4.1 Sources and formats for characterization parameters Different sensor tags display characterization parameters differently. On older sensors, the sensor tag may not contain all the required parameters. Sample sensor tags Sample sensor tags are shown in the following illustrations: • Older curved-tube sensors (all sensors except T-Series): see Figure 2-1 • Newer curved-tube sensors (all sensors except T-Series): see Figure 2-2 • Older straight-tube sensors (T-Series): see Figure 2-3 • Newer straight-tube sensors (T-Series): see Figure 2-4 Figure 2-1: Tag on older curved-tube sensors (all sensors except T-Series) 10 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Quick start Figure 2-2: Tag on newer curved-tube sensors (all sensors except T-Series) Figure 2-3: Tag on older straight-tube sensor (T-Series) Figure 2-4: Tag on newer straight-tube sensor (T-Series) Configuration and Use Manual 11 Quick start Density calibration parameters (D1, D2, K1, K2, FD, DT, TC) If your sensor tag does not show a D1 or D2 value: • For D1, enter the Dens A or D1 value from the calibration certificate. This value is the line-condition density of the low-density calibration fluid. Micro Motion uses air. If you cannot find a Dens A or D1 value, enter 0.001 g/cm3. • For D2, enter the Dens B or D2 value from the calibration certificate. This value is the line-condition density of the high-density calibration fluid. Micro Motion uses water. If you cannot find a Dens B or D2 value, enter 0.998 g/cm3. If your sensor tag does not show a K1 or K2 value: • For K1, enter the first 5 digits of the density calibration factor. In the sample tag, this value is shown as 12500 (see Figure 2-1). • For K2, enter the second 5 digits of the density calibration factor. In the sample tag, this value is shown as 14286 (see Figure 2-1). If your sensor does not show an FD value, contact Micro Motion customer service. If your sensor tag does not show a DT or TC value, enter the last 3 digits of the density calibration factor. In the sample tag, this value is shown as 4.44 (see Figure 2-1). Flow calibration parameters (FCF, FT) Two separate values are used to describe flow calibration: a 6-character FCF value and a 4character FT value. Both values contain decimal points. During characterization, these may be entered as two values or as a single 10-character string. The 10-character string is called either Flowcal or FCF. If your sensor tag shows the FCF and the FT values separately and you need to enter a single value, concatenate the two values to form the single parameter value. If your sensor tag shows a concatenated Flowcal or FCF value and you need to enter the FCF and the FT values separately, split the concatenated value: • FCF = The first 6 characters, including the decimal point • FT = The last 4 characters, including the decimal point Example: Concatenating FCF and FT FCF = x.xxxx FT = y.yy Flow calibration parameter: x.xxxxy.yy Example: Splitting the concatenated Flowcal or FCF value Flow calibration parameter: x.xxxxy.yy FCF = x.xxxx FT = y.yy 12 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Quick start 2.5 Verify mass flow measurement Check to see that the mass flow rate reported by the transmitter is accurate. You can use any available method. • Read the value for Mass Flow Rate on the transmitter display. • Connect to the transmitter with ProLink II and read the value for Mass Flow Rate in the Process Variables window (ProLink > Process Variables). • Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in the Process Variables panel. • Connect to the transmitter with the Field Communicator and read the value for Mass Flow Rate in the Process Variables menu (On-Line Menu > Overview > Primary Purpose Variables). Postrequisites If the reported mass flow rate is not accurate: 2.6 • Check the characterization parameters. • Review the troubleshooting suggestions for flow measurement issues. See Section 12.3. Verify the zero Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy. The zero verification procedure analyzes the Live Zero value under conditions of zero flow, and compares it to the Zero Stability range for the sensor. If the average Live Zero value is within a reasonable range, the zero value stored in the transmitter is valid. Performing a field calibration will not improve measurement accuracy. 2.6.1 Verify the zero using ProLink II Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy. Important In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless one of the following is true: • The zero is required by site procedures. • The stored zero value fails the zero verification procedure. Prerequisites ProLink II v2.94 or later Configuration and Use Manual 13 Quick start Important Do not verify the zero or zero the flowmeter if a high-severity alarm is active. Correct the problem, then verify the zero or zero the flowmeter. You may verify the zero or zero the flowmeter if a lowseverity alarm is active. Procedure 1. Prepare the flowmeter: a. Allow the flowmeter to warm up for at least 20 minutes after applying power. b. Run the process fluid through the sensor until the sensor temperature reaches the normal process operating temperature. c. Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if available. d. Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of process fluid. 2. Choose ProLink > Calibration > Zero Verification and Calibration > Verify Zero and wait until the procedure completes. 3. If the zero verification procedure fails: a. Confirm that the sensor is completely blocked in, that flow has stopped, and that the sensor is completely full of process fluid. b.

If it fails again, zero the flowmeter. For instructions on zeroing the flowmeter, see Section 11.3. Postrequisites Restore normal flow through the sensor by opening the valves. 2.6.2 Verify the zero using ProLink III Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy. Important In most cases, the factory zero is more accurate than the field zero. Do not zero the flowmeter unless one of the following is true: • The zero is required by site procedures. • The stored zero value fails the zero verification procedure.

Unit = microseconds. Factory Zero The zero value obtained at the factory, under laboratory conditions. Field Zero The zero value obtained by performing a zero calibration outside the factory. Prior Zero The zero value stored in the transmitter at the time a field zero calibration is begun. May be the factory zero or a previous field zero. Manual Zero The zero value stored in the transmitter, typically obtained from a zero calibration procedure. It may also be configured manually. Also called “mechanical zero” or “stored zero.” Configuration and Use Manual 15 Quick start Table 2-2: Terminology used with zero verification and zero calibration (continued) Term Definition Live Zero The real-time bidirectional mass flow rate with no flow damping or mass flow cutoff applied. An adaptive damping value is applied only when the mass flow rate changes dramatically over a very short interval. Unit = configured mass flow measurement unit. Zero Stability A laboratory-derived value used to calculate the expected accuracy for a sensor. Under laboratory conditions at zero flow, the average flow rate is expected to fall within the range defined by the Zero Stability value (0 ± Zero Stability). Each sensor size and model has a unique Zero Stability value. Statistically, 95% of all data points should fall within the range defined by the Zero Stability value. Zero Calibration The procedure used to determine the zero value. Zero Time The time period over which the Zero Calibration procedure is performed. Unit = seconds. Field Verification Zero A 3-minute running average of the Live Zero value, calculated by the transmitter. Unit = configured mass flow measurement unit. Zero Verification A procedure used to evaluate the stored zero and determine whether or not a field zero can improve measurement accuracy. 16 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configuration and commissioning Part II Configuration and commissioning Chapters covered in this part: • Introduction to configuration and commissioning • • • • • Configure process measurement Configure device options and preferences Integrate the meter with the control system Completing the configuration Set up the Weights & Measures application Configuration and Use Manual 17 Configuration and commissioning 18 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Introduction to configuration and commissioning 3 Introduction to configuration and commissioning Topics covered in this chapter: • • • • • 3.1 Configuration flowchart Default values and ranges Enable access to the off-line menu of the display Disable write-protection on the transmitter configuration Restore the factory configuration Configuration flowchart Use the following flowchart as a general guide to the configuration and commissioning process.

A special measurement unit is calculated from an existing measurement unit using a conversion factor. Note Although you cannot define a special measurement unit using the display, you can use the display to select an existing special measurement unit, and to view process data using the special measurement unit. Procedure 1. Specify Base Mass Unit. Base Mass Unit is the existing mass unit that the special unit will be based on. 2. Specify Base Time Unit. Base Time Unit is the existing time unit that the special unit will be based on. 3. Calculate Mass Flow Conversion Factor as follows: a. x base units = y special units b. Mass Flow Conversion Factor = x/y 4. Enter Mass Flow Conversion Factor. 5. Set Mass Flow Label to the name you want to use for the mass flow unit. 6. Set Mass Total Label to the name you want to use for the mass total and mass inventory unit. The special measurement unit is stored in the transmitter. You can configure the transmitter to use the special measurement unit at any time. Example: Defining a special measurement unit for mass flow You want to measure mass flow in ounces per second (oz/sec). 1. Set Base Mass Unit to Pounds (lb). 2. Set Base Time Unit to Seconds (sec). 3. Calculate Mass Flow Conversion Factor: Configuration and Use Manual 25 Configure process measurement a. 1 lb/sec = 16 oz/sec b. Mass Flow Conversion Factor = 1/16 = 0.0625 4.1.2 4. Set Mass Flow Conversion Factor to 0.0625. 5. Set Mass Flow Label to oz/sec. 6. Set Mass Total Label to oz. Configure Flow Damping Display Not available ProLink II ProLink > Configuration > Flow > Flow Damp ProLink III Device Tools > Configuration > Process Measurement > Flow Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Damping Overview Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value. Procedure Set Flow Damping to the value you want to use. The default value is 0.8 seconds. The range depends on the core processor type and the setting of Update Rate, as shown in the following table. Core processor type Update Rate setting Flow Damping range Standard Normal 0 to 51.2 seconds Special 0 to 10.24 seconds Not applicable 0 to 51.2 seconds Enhanced Tips • A high damping value makes the process variable appear smoother because the reported value changes slowly. • A low damping value makes the process variable appear more erratic because the reported value changes more quickly. • The combination of a high damping value and rapid, large changes in flow rate can result in increased measurement error. • Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time. 26 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configure process measurement • In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value. • For gas applications, Micro Motion recommends setting Flow Damping to 2.56 or higher. The value you enter is automatically rounded down to the nearest valid value. Valid damping values are shown in the following table. Table 4-2: Valid values for Flow Damping Core processor type Update Rate setting Valid damping values Standard Normal 0, 0.2, 0.4, 0.8, ... 51.2 Special 0, 0.04, 0.08, 0.16, ... 10.24 Not applicable 0, 0.2, 0.4, 0.8, ... 51.2 Enhanced Effect of Flow Damping on volume measurement Flow Damping affects volume measurement for liquid volume data. Flow Damping also affects volume measurement for gas standard volume data. The transmitter calculates volume data from the damped mass flow data. Interaction between Flow Damping and Added Damping In some circumstances, both Flow Damping and Added Damping are applied to the reported mass flow value. Flow Damping controls the rate of change in flow process variables. Added Damping controls the rate of change reported via the mA output. If mA Output Process Variable is set to Mass Flow Rate, and both Flow Damping and Added Damping are set to non-zero values, flow damping is applied first, and the added damping calculation is applied to the result of the first calculation. 4.1.3 Configure Mass Flow Cutoff Display Not available ProLink II ProLink > Configuration > Flow > Mass Flow Cutoff ProLink III Device Tools > Configuration > Process Measurement > Flow Field Communicator Configure > Manual Setup > Measurements > Flow > Mass Flow Cutoff Overview Mass Flow Cutoff specifies the lowest mass flow rate that will be reported as measured. All mass flow rates below this cutoff will be reported as 0. Configuration and Use Manual 27 Configure process measurement Procedure Set Mass Flow Cutoff to the value you want to use. The default value for Mass Flow Cutoff is 0.0 g/sec or a sensor-specific value set at the factory. The recommended setting is 0.05% of the sensor's rated maximum flow rate or a value below the highest expected flow rate. Do not set Mass Flow Cutoff to 0.0 g/sec. Effect of Mass Flow Cutoff on volume measurement Mass Flow Cutoff does not affect volume measurement. Volume data is calculated from the actual mass data rather than the reported value. Interaction between Mass Flow Cutoff and AO Cutoff Mass Flow Cutoff defines the lowest mass flow value that the transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be reported via the mA output. If mA Output Process Variable is set to Mass Flow Rate, the mass flow rate reported via the mA output is controlled by the higher of the two cutoff values. Mass Flow Cutoff affects all reported values and values used in other transmitter behavior (e.g., events defined on mass flow). AO Cutoff affects only mass flow values reported via the mA output. Example: Cutoff interaction with AO Cutoff lower than Mass Flow Cutoff Configuration: • mA Output Process Variable: Mass Flow Rate • Frequency Output Process Variable: Mass Flow Rate • AO Cutoff: 10 g/sec • Mass Flow Cutoff: 15 g/sec Result: If the mass flow rate drops below 15 g/sec, mass flow will be reported as 0, and 0 will be used in all internal processing. Example: Cutoff interaction with AO Cutoff higher than Mass Flow Cutoff Configuration: • mA Output Process Variable: Mass Flow Rate • Frequency Output Process Variable: Mass Flow Rate • AO Cutoff: 15 g/sec • Mass Flow Cutoff: 10 g/sec Result: • If the mass flow rate drops below 15 g/sec but not below 10 g/sec: - 28 The mA output will report zero flow. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configure process measurement • 4.2 The frequency output will report the actual flow rate, and the actual flow rate will be used in all internal processing. If the mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0 will be used in all internal processing. Configure volume flow measurement for liquid applications The volume flow measurement parameters control how liquid volume flow is measured and reported. The volume flow measurement parameters include: • Volume Flow Type • Volume Flow Measurement Unit • Volume Flow Cutoff Restriction You cannot implement both liquid volume flow and gas standard volume flow at the same time. You must choose one or the other. 4.2.1 Configure Volume Flow Type for liquid applications Display Not available ProLink II ProLink > Configuration > Flow > Vol Flow Type > Liquid Volume ProLink III Device Tools > Configuration > Process Measurement > Flow Field Communicator Configure > Manual Setup > Measurements > GSV > Volume Flow Type > Liquid Overview Volume Flow Type controls whether liquid or gas standard volume flow measurement will be used.

Configure Volume Flow Cutoff Display Not available ProLink II ProLink > Configuration > Flow > Vol Flow Cutoff ProLink III Device Tools > Configuration > Process Measurement > Flow Field Communicator Configure > Manual Setup > Measurements > Flow > Volume Flow Cutoff Overview Volume Flow Cutoff specifies the lowest volume flow rate that will be reported as measured. All volume flow rates below this cutoff are reported as 0. Procedure Set Volume Flow Cutoff to the value you want to use. The default value for Volume Flow Cutoff is 0.0 l/sec (liters per second). The lower limit is 0. The upper limit is the sensor’s flow calibration factor, in units of l/sec, multiplied by 0.2. Interaction between Volume Flow Cutoff and AO Cutoff Volume Flow Cutoff defines the lowest liquid volume flow value that the transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be reported via the mA output. If mA Output Process Variable is set to Volume Flow Rate, the volume flow rate reported via the mA output is controlled by the higher of the two cutoff values. Volume Flow Cutoff affects both the volume flow values reported via the outputs and the volume flow values used in other transmitter behavior (e.g., events defined on the volume flow). AO Cutoff affects only flow values reported via the mA output. Example: Cutoff interaction with AO Cutoff lower than Volume Flow Cutoff Configuration: • mA Output Process Variable: Volume Flow Rate • Frequency Output Process Variable: Volume Flow Rate • AO Cutoff: 10 l/sec • Volume Flow Cutoff: 15 l/sec Configuration and Use Manual 33 Configure process measurement Result: If the volume flow rate drops below 15 l/sec, volume flow will be reported as 0, and 0 will be used in all internal processing. Example: Cutoff interaction with AO Cutoff higher than Volume Flow Cutoff Configuration: • mA Output Process Variable: Volume Flow Rate • Frequency Output Process Variable: Volume Flow Rate • AO Cutoff: 15 l/sec • Volume Flow Cutoff: 10 l/sec Result: • • 4.3 If the volume flow rate drops below 15 l/sec but not below 10 l/sec: - The mA output will report zero flow. - The frequency output will report the actual flow rate, and the actual flow rate will be used in all internal processing. If the volume flow rate drops below 10 l/sec, both outputs will report zero flow, and 0 will be used in all internal processing. Configure gas standard volume (GSV) flow measurement The gas standard volume (GSV) flow measurement parameters control how gas standard volume flow is measured and reported.

All gas standard volume flow rates below this cutoff will be reported as 0. Procedure Set Gas Standard Volume Flow Cutoff to the value you want to use. The default value for Gas Standard Volume Flow Cutoff is 0.0. The lower limit is 0.0. There is no upper limit. Interaction between Gas Standard Volume Flow Cutoff and AO Cutoff Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that the transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be reported via the mA output. If mA Output Process Variable is set to Gas Standard Volume Flow Rate, the volume flow rate reported via the mA output is controlled by the higher of the two cutoff values. Gas Standard Volume Flow Cutoff affects both the gas standard volume flow values reported via outputs and the gas standard volume flow values used in other transmitter behavior (e.g., events defined on gas standard volume flow). AO Cutoff affects only flow values reported via the mA output. Example: Cutoff interaction with AO Cutoff lower than Gas Standard Volume Flow Cutoff Configuration: • mA Output Process Variable for the primary mA output: Gas Standard Volume Flow Rate • Frequency Output Process Variable: Gas Standard Volume Flow Rate • AO Cutoff for the primary mA output: 10 SLPM (standard liters per minute) • Gas Standard Volume Flow Cutoff: 15 SLPM Result: If the gas standard volume flow rate drops below 15 SLPM, the volume flow will be reported as 0, and 0 will be used in all internal processing.

If the gas standard volume flow rate drops below 10 SLPM, both outputs will report zero flow, and 0 will be used in all internal processing. Configure Flow Direction Display Not available ProLink II ProLink > Configuration > Flow > Flow Direction ProLink III Device Tools > Configuration > Process Measurement > Flow Field Communicator Configure > Manual Setup > Measurements > Flow > Flow Direction Overview Flow Direction controls how forward flow and reverse flow affect flow measurement and reporting. Flow Direction is defined with respect to the flow arrow on the sensor: • Forward flow (positive flow) moves in the direction of the flow arrow on the sensor. • Reverse flow (negative flow) moves in the direction opposite to the flow arrow on the sensor. Tip Micro Motion sensors are bidirectional. Measurement accuracy is not affected by actual flow direction or the setting of the Flow Direction parameter.

Effect of Flow Direction on mA outputs Flow Direction affects how the transmitter reports flow values via the mA outputs. The mA outputs are affected by Flow Direction only if mA Output Process Variable is set to a flow variable. Flow Direction and mA outputs The effect of Flow Direction on the mA outputs depend on Lower Range Value configured for the mA output: • If Lower Range Value is set to 0, see Figure 4-1. • If Lower Range Value is set to a negative value, see Figure 4-2.

Example: Flow Direction = Forward and Lower Range Value < 0 Configuration: • Flow Direction = Forward • Lower Range Value = −100 g/sec • Upper Range Value = +100 g/sec Result: • Under conditions of zero flow, the mA output is 12 mA. • Under conditions of forward flow, for flow rates between 0 and +100 g/sec, the mA output varies between 12 mA and 20 mA in proportion to (the absolute value of) the flow rate. • Under conditions of forward flow, if (the absolute value of) the flow rate equals or exceeds 100 g/sec, the mA output is proportional to the flow rate up to 20.5 mA, and will be level at 20.5 mA at higher flow rates. • Under conditions of reverse flow, for flow rates between 0 and −100 g/sec, the mA output varies between 4 mA and 12 mA in inverse proportion to the absolute value of the flow rate. • Under conditions of reverse flow, if the absolute value of the flow rate equals or exceeds 100 g/sec, the mA output is inversely proportional to the flow rate down to 3.8 mA, and will be level at 3.8 mA at higher absolute values.

Procedure 1. Set Slug Low Limit to the lowest density value that is considered normal in your process. Values below this will cause the transmitter to perform the configured slug flow action. Typically, this value is the lowest density value in the normal range of your process. Tip Gas entrainment can cause your process density to drop temporarily. To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug Low Limit slightly below your expected lowest process density. You must enter Slug Low Limit in g/cm3, even if you configured another unit for density measurement. The default value for Slug Low Limit is 0.0 g/cm3. The range is 0.0 to 10.0 g/cm3. 2. Set Slug High Limit to the highest density value that is considered normal in your process. Values above this will cause the transmitter to perform the configured slug flow action. Typically, this value is the highest density value in the normal range of your process. Tip To reduce the occurrence of slug flow alarms that are not significant to your process, set Slug High Limit slightly above your expected highest process density. You must enter Slug High Limit in g/cm3, even if you configured another unit for density measurement. Configuration and Use Manual 47 Configure process measurement The default value for Slug High Limit is 5.0 g/cm3. The range is 0.0 to 10.0 g/cm3. 3. Set Slug Duration to the number of seconds that the transmitter will wait for a slug flow condition to clear before performing the configured slug flow action. The default value for Slug Duration is 0.0 seconds. The range is 0.0 to 60.0 seconds. Slug flow detection and reporting Slug flow is typically used as an indicator of two-phase flow (gas in a liquid process or liquid in a gas process). Two-phase flow can cause a variety of process control issues. By configuring the slug flow parameters appropriately for your application, you can detect process conditions that require correction. Tip To decrease the occurrence of slug flow alarms, lower Slug Low Limit or raise Slug High Limit. A slug flow condition occurs whenever the measured density goes below Slug Low Limit or above Slug High Limit. If this occurs: • A slug flow alarm is posted to the active alarm log. • All outputs that are configured to represent flow rate hold their last “pre-slug flow” value for the configured Slug Duration. If the slug flow condition clears before Slug Duration expires: • Outputs that represent flow rate revert to reporting actual flow. • The slug flow alarm is deactivated, but remains in the active alarm log until it is acknowledged. If the slug flow condition does not clear before Slug Duration expires, the outputs that represent flow rate report a flow rate of 0. If Slug Duration is set to 0.0 seconds, the outputs that represent flow rate will report a flow rate of 0 as soon as slug flow is detected. 4.5.3 Configure Density Damping Display Not available ProLink II ProLink > Configuration > Density > Density Damping ProLink III Device Tools > Configuration > Process Measurement > Density Field Communicator Configure > Manual Setup > Measurements > Density > Density Damping 48 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configure process measurement Overview Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value. Procedure Set Density Damping to the value you want to use. The default value is 1.6 seconds. The range depends on the core processor type and the setting of Update Rate, as shown in the following table: Core processor type Update Rate setting Density Damping range Standard Normal 0 to 51.2 seconds Special 0 to 10.24 seconds Not applicable 0 to 40.96 seconds Enhanced Tips • A high damping value makes the process variable appear smoother because the reported value changes slowly. • A low damping value makes the process variable appear more erratic because the reported value changes more quickly. • Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time. • In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value. The value you enter is automaticaly rounded down to the nearest valid value. The valid values for Density Damping depend on the setting of Update Rate. Table 4-11: Valid values for Density Damping Core processor type Update Rate setting Valid damping values Standard Normal 0, 0.2, 0.4, 0.8, ... 51.2 Special 0, 0.04, 0.08, 0.16, ... 10.24 Not applicable 0, 0.04, 0.08, 0.16, ... 40.96 Enhanced Effect of Density Damping on volume measurement Density Damping affects liquid volume measurement. Liquid volume values are calculated from the damped density value rather than the measured density value. Density Damping does not affect gas standard volume measurement. Configuration and Use Manual 49 Configure process measurement Interaction between Density Damping and Added Damping In some circumstances, both Density Damping and Added Damping are applied to the reported density value. Density Damping controls the rate of change in the density process variable. Added Damping controls the rate of change reported via the mA output. If mA Output Process Variable is set to Density, and both Density Damping and Added Damping are set to non-zero values, density damping is applied first, and the added damping calculation is applied to the result of the first calculation. 4.5.4 Configure Density Cutoff Display Not available ProLink II ProLink > Configuration > Density > Low Density Cutoff ProLink III Device Tools > Configuration > Process Measurement > Density Field Communicator Configure > Manual Setup > Measurements > Density > Density Cutoff Overview Density Cutoff specifies the lowest density value that will be reported as measured. All density values below this cutoff will be reported as 0. Procedure Set Density Cutoff to the value you want to use. The default value for Density Cutoff is 0.2 g/cm3. The range is 0.0 g/cm3 to 0.5 g/cm3. Effect of Density Cutoff on volume measurement Density Cutoff affects liquid volume measurement. If the density value goes below Density Cutoff, the volume flow rate is reported as 0. Density Cutoff does not affect gas standard volume measurement. Gas standard volume values are always calculated from the value configured for Standard Gas Density. 4.6 Configure temperature measurement The temperature measurement parameters control how temperature data from the sensor is reported. Temperature data is used to compensate for the effect of temperature on the sensor tubes during flow measurement .

The default value is 4.8 seconds. The range is 0.0 to 76.8 seconds. Tips • A high damping value makes the process variable appear smoother because the reported value changes slowly. • A low damping value makes the process variable appear more erratic because the reported value changes more quickly. • Whenever the damping value is non-zero, the reported measurement will lag the actual measurement because the reported value is being averaged over time. • In general, lower damping values are preferable because there is less chance of data loss, and less lag time between the actual measurement and the reported value.

Effect of Temperature Damping on process measurement Temperature Damping affects the response speed for temperature compensation with fluctuating temperatures. Temperature compensation adjusts the process measurement to compensate for the effect of temperature on the sensor tube. Temperature Damping affects petroleum measurement process variables only if the transmitter is configured to use temperature data from the sensor. If an external temperature value is used for petroleum measurement, Temperature Damping does not affect petroleum measurement process variables. Temperature Damping affects concentration measurement process variables only if the transmitter is configured to use temperature data from the sensor. If an external temperature value is used for concentration measurement, Temperature Damping does not affect concentration measurement process variables. 52 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configure process measurement 4.7 Configure the petroleum measurement application The petroleum measurement application enables Correction for the effect of Temperature on the volume of Liquids (CTL), by calculating and applying a Volume Correction Factor (VCF) to volume measurement.

Update Rate = Special produces faster and “noisier” response to changes in the process. Do not use Special mode unless required by your application. Tip For systems with a standard core processor, Special mode can improve performance for applications with entrained air or Empty-Full-Empty conditions. This does not apply to systems with an enhanced core processor. Prerequisites Before setting Update Rate to Special: • Check the effects of Special mode on specific process variables. • Contact Micro Motion. Procedure 1. Set Update Rate as desired. Option Description Normal All process data is polled at the rate of 20 times per second (20 Hz). All process variables are calculated at 20 Hz. This option is appropriate for most applications. Special A single, user-specified process variable is polled at the rate of 100 times per second (100 Hz). Other process data is polled at 6.25 Hz). Some process, diagnostic, and calibration data is not polled. All available process variables are calculated at 100 Hz. Use this option only if required by your application.

Restriction Fault Timeout is applied only to the following alarms (listed by Status Alarm Code): A003, A004, A005, A008, A016, A017, A033. For all other alarms, fault actions are performed as soon as the alarm is detected. Procedure Set Fault Timeout as desired. The default value is 0 seconds. The range is 0 to 60 seconds. If you set Fault Timeout to 0, fault actions are performed as soon as the alarm condition is detected. The fault timeout period begins when the transmitter detects an alarm condition. During the fault timeout period, the transmitter continues to report its last valid measurements. If the fault timeout period expires while the alarm is still active, the fault actions are performed. If the alarm condition clears before the fault timeout expires, no fault actions are performed. Tip ProLink II allows you to set Fault Timeout in two locations. However, there is only one parameter, and the same setting is applied to all outputs. 5.5.2 Configure Status Alarm Severity Display Not available ProLink II ProLink > Configuration > Alarm > Severity ProLink III Device Tools > Configuration > Alert Severity Field Communicator Configure > Alert Setup > Alert Severity > Set Alert Severity 90 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Configure device options and preferences Overview Use Status Alarm Severity to control the fault actions that the transmitter performs when it detects an alarm condition.

The channel configuration must match the wiring at the transmitter terminals. Prerequisites To avoid causing process errors: • Configure the channels before configuring the outputs. • Before changing the channel configuration, ensure that all control loops affected by the channel are under manual control. Procedure Set Channel B as desired. Option Description Frequency output Channel B will operate as a frequency output. Discrete output Channel B will operate as a discrete output. Configuration and Use Manual 99 Integrate the meter with the control system Postrequisites For each channel that you configured, perform or verify the corresponding input or output configuration. When the configuration of a channel is changed, the channel’s behavior will be controlled by the configuration that is stored for the selected input or output type, and the stored configuration may not be appropriate for your process. After verifying channel and output configuration, return the control loop to automatic control. 6.2 Configure the mA output The mA output is used to report the configured process variable. The mA output parameters control how the process variable is reported. Your transmitter has two mA outputs: Channel A and Channel C. The mA output parameters include: • mA Output Process Variable • Lower Range Value (LRV) and Upper Range Value (URV) • AO Cutoff • Added Damping • AO Fault Action and AO Fault Value Important Whenever you change an mA output parameter, verify all other mA output parameters before returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored values, and these values may not be appropriate for your application. 6.2.1 Configure mA Output Process Variable Display • OFF-LINE MAINT > OFF-LINE CONFG > IO > CH A • OFF-LINE MAINT > OFF-LINE CONFG > IO > CH C ProLink II ProLink > Configuration > Analog Output ProLink III Device Tools > Configuration > I/O > Outputs > mA Output Field Communicator • Configure > Manual Setup > Inputs/Outputs > mA Output 1 • Configure > Manual Setup > Inputs/Outputs > mA Output 2 Overview Use mA Output Process Variable to select the variable that is reported over the mA output.

Default settings are as follows: • Primary mA output: Mass Flow Rate • Secondary mA output: Density Options for mA Output Process Variable The transmitter provides a basic set of options for mA Output Process Variable, plus several application-specific options. Different communications tools may use different labels for the options.

For example, if you set mA Output Process Variable to Mass Flow Rate and change the LRV and URV, then you set mA Output Process Variable to Density, and finally you change mA Output Process Variable back to Mass Flow Rate, LRV and URV for Mass Flow Rate reset to the values that you configured. In earlier versions of the transmitter software, LRV and URV reset to the factory default values. Procedure Set LRV and URV as desired. • LRV is the value of mA Output Process Variable represented by an output of 4 mA. The default value for LRV depends on the setting of mA Output Process Variable. Enter LRV in the measurement units that are configured for mA Output Process Variable. • URV is the value of mA Output Process Variable represented by an output of 20 mA. The default value for URV depends on the setting of mA Output Process Variable. Enter URV in the measurement units that are configured for mA Output Process Variable. Tips For best performance: • Set LRV ≥ LSL (lower sensor limit). • Set URV ≤ USL (upper sensor limit). • Set these values so that the difference between URV and LRV is ≥ Min Span (minimum span). Defining URV and LRV within the recommended values for Min Span, LSL, and USL ensures that the resolution of the mA output signal is within range of the bit precision of the D/A converter. Note You can set URV below LRV. For example, you can set URV to 50 and LRV to 100. The mA output uses a range of 4–20 mA to represent mA Output Process Variable. Between LRV and URV, the mA output is linear with the process variable. If the process variable drops below LRV or rises above URV, the transmitter posts an output saturation alarm. Default values for Lower Range Value (LRV) and Upper Range Value (URV) Each option for mA Output Process Variable has its own LRV and URV. If you change the configuration of mA Output Process Variable, the corresponding LRV and URV are loaded and used.

Any flow rates below AO Cutoff will be reported as 0. Restriction AO Cutoff is applied only if mA Output Process Variable is set to Mass Flow Rate, Volume Flow Rate, or Gas Standard Volume Flow Rate. If mA Output Process Variable is set to a different process variable, AO Cutoff is not configurable, and the transmitter does not implement the AO cutoff function. Procedure Set AO Cutoff as desired. The default values for AO Cutoff are as follows: • Primary mA output: 0.0 g/sec • Secondary mA output: Not-A-Number 104 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Integrate the meter with the control system Tip For most applications, the default value of AO Cutoff should be used. Contact Micro Motion customer service before changing AO Cutoff. Interaction between AO Cutoff and process variable cutoffs When mA Output Process Variable is set to a flow variable (for example, mass flow rate or volume flow rate), AO Cutoff interacts with Mass Flow Cutoff or Volume Flow Cutoff. The transmitter puts the cutoff into effect at the highest flow rate at which a cutoff is applicable. Example: Cutoff interaction Configuration: • mA Output Process Variable = Mass Flow Rate • Frequency Output Process Variable = Mass Flow Rate • AO Cutoff = 10 g/sec • Mass Flow Cutoff = 15 g/sec Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will report zero flow. Example: Cutoff interaction Configuration: • mA Output Process Variable = Mass Flow Rate • Frequency Output Process Variable = Mass Flow Rate • AO Cutoff = 15 g/sec • Mass Flow Cutoff = 10 g/sec Result: • • If the mass flow rate drops below 15 g/sec but not below 10 g/sec: - The mA output will report zero flow. - The frequency output will report the actual flow rate. If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.

Damping Value specifies the time period (in seconds) over which the transmitter will spread changes in the reported process variable. At the end of the interval, the reported process variable will reflect 63% of the change in the actual measured value. Added Damping controls the amount of damping that will be applied to the mA output. It affects the reporting of mA Output Process Variable through the mA output only. It does not affect the reporting of that process variable via any other method (e.g., the frequency output or digital communications), or the value of the process variable used in calculations. Note Added Damping is not applied if the mA output is fixed (for example, during loop testing) or if the mA output is reporting a fault. Added Damping is applied while sensor simulation is active. Procedure Set Added Damping to the desired value. The default value is 0.0 seconds. When you specify a value for Added Damping, the transmitter automatically rounds the value down to the nearest valid value. Note Added Damping values are affected by the setting of Update Rate and 100 Hz Variable. Table 6-3: Valid values for Added Damping Setting of Update Rate Process variable Update rate in effect Normal N/A 20 Hz 0.0, 0.1, 0.3, 0.75, 1.6, 3.3, 6.5, 13.5, 27.5, 55, 110, 220, 440 Special 100 Hz variable (if assigned to the mA output) 100 Hz 0.0, 0.04, 0.12, 0.30, 0.64, 1.32, 2.6, 5.4, 11, 22, 44, 88, 176, 350 106 Valid values for Added Damping Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Integrate the meter with the control system Table 6-3: Valid values for Added Damping (continued) Setting of Update Rate Process variable 100 Hz variable (if not assigned to the mA output) Update rate in effect 6.25 Hz Valid values for Added Damping 0.0, 0.32, 0.96, 2.40, 5.12, 10.56, 20.8, 43.2, 88, 176, 352 All other process variables Interaction between Added Damping and process variable damping When mA Output Process Variable is set to a flow variable, density, or temperature, Added Damping interacts with Flow Damping, Density Damping, or Temperature Damping. If multiple damping parameters are applicable, the effect of damping the process variable is calculated first, and the added damping calculation is applied to the result of that calculation. Example: Damping interaction Configuration: • Flow Damping = 1 second • mA Output Process Variable = Mass Flow Rate • Added Damping = 2 seconds Result: A change in the mass flow rate will be reflected in the mA output over a time period that is greater than 3 seconds. The exact time period is calculated by the transmitter according to internal algorithms which are not configurable. 6.2.5 Configure mA Output Fault Action and mA Output Fault Level Display Not available ProLink II • ProLink > Configuration > Analog Output > Primary/Secondary Output > AO Fault Action • ProLink > Configuration > Analog Output > Primary/Secondary Output > AO Fault Level ProLink III Device Tools > Configuration > Fault Processing Field Communicator • Configure > Manual Setup > Inputs/Outputs > mA Output 1 > MA01 Fault Settings • Configure > Manual Setup > Inputs/Outputs > mA Output 2 > MA02 Fault Settings Overview mA Output Fault Action controls the behavior of the mA output if the transmitter encounters an internal fault condition.

If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital Communications Fault Action to None. If you do not, the output will not report actual process data, and this may result in measurement errors or unintended consequences for your process. Restriction If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency Output Fault Action to None. If you try to do this, the transmitter will not accept the configuration. 108 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Integrate the meter with the control system 6.3 Configure the frequency output The frequency output is used to report a process variable. The frequency output parameters control how the process variable is reported. Your transmitter may have zero or one frequency output: Channel B can be configured as a frequency output or a discrete output. The frequency output parameters include: • Frequency Output Process Variable • Frequency Output Polarity • Frequency Output Scaling Method • Frequency Output Maximum Pulse Width • Frequency Output Fault Action and Frequency Output Fault Value Important Whenever you change a frequency output parameter, verify all other frequency output parameters before returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored values, and these values may not be appropriate for your application. 6.3.1 Configure Frequency Output Process Variable Display OFF-LINE MAINT > OFF-LINE CONFG > IO > CH B > SET FO > FO SRC ProLink II ProLink > Configuration > Frequency/Discrete Output > Frequency > Tertiary Variable ProLink III Device Tools > Configuration > I/O > Outputs > Frequency Output Field Communicator Configure > Manual Setup > Inputs/Outputs > Frequency Output > FO Settings > Third Variable Overview Frequency Output Process Variable controls the variable that is reported over the frequency output. Prerequisites If you plan to configure the output to report volume flow, ensure that you have set Volume Flow Type as desired: Liquid or Gas Standard Volume. If you plan to configure an output to report a concentration measurement process variable, ensure that the concentration measurement application is configured so that the desired variable is available.

Set Frequency Output Scaling Method as required by your frequency receiving device. Procedure 1. 2. Set Frequency Output Scaling Method. Option Description Frequency=Flow (default) Frequency calculated from flow rate Pulses/Unit A user-specified number of pulses represents one flow unit Units/Pulse A pulse represents a user-specified number of flow units Set additional required parameters. • If you set Frequency Output Scaling Method to Frequency=Flow, set Rate Factor and Frequency Factor. Configuration and Use Manual 111 Integrate the meter with the control system • If you set Frequency Output Scaling Method to Pulses/Unit, define the number of pulses that will represent one flow unit. • If you set Frequency Output Scaling Method to Units/Pulse, define the number of units that each pulse will indicate. Calculate frequency from flow rate The Frequency=Flow option is used to customize the frequency output for your application when you do not know appropriate values for Units/Pulse or Pulses/Unit. If you specify Frequency=Flow, you must provide values for Rate Factor and Frequency Factor: Rate Factor The maximum flow rate that you want the frequency output to report. Above this rate, the transmitter will report A110: Frequency Output Saturated. Frequency Factor A value calculated as follows: FrequencyFactor = RateFactor T xN where: T Factor to convert selected time base to seconds N Number of pulses per flow unit, as configured in the receiving device The resulting Frequency Factor must be within the range of the frequency output (0 to 10,000 Hz): • If Frequency Factor is less than1 Hz,reconfigure the receiving device for a higher pulses/unit setting. • If Frequency Factor is greater than 10,000 Hz, reconfigure the receiving device for a lower pulses/unit setting. Tip If Frequency Output Scale Method is set to Frequency=Flow, and Frequency Output Maximum Pulse Width is set to a non-zero value, Micro Motion recommends setting Frequency Factor to a value below 200 Hz. Example: Configure Frequency=Flow You want the frequency output to report all flow rates up to 2000 kg/min. The frequency receiving device is configured for 10 pulses/kg.

The discrete output parameters control which condition is reported and how it is reported. Your transmitter may have zero or one discrete output: Channel B can be configured as a frequency output or a discrete output. The discrete output parameters include: • Discrete Output Source • Discrete Output Polarity • Discrete Output Fault Action Restriction Before you can configure the discrete output, you must configure a channel to operate as a discrete output. Important Whenever you change a discrete output parameter, verify all other discrete output parameters before returning the flowmeter to service.

The flow switch is implemented with a user-configurable hysteresis. Procedure 1. Set Discrete Output Source to Flow Switch, if you have not already done so. 2. Set Flow Switch Variable to the flow variable that you want to use to control the flow switch. 3. Set Flow Switch Setpoint to the value at which the flow switch will be triggered (after Hysteresis is applied). • If the flow rate is below this value, the discrete output is ON. • If the flow rate is above this value, the discrete output is OFF. 4. Set Hysteresis to the percentage of variation above and below the setpoint that will operate as a deadband. Hysteresis defines a range around the setpoint within which the flow switch will not change. The default is 5%. The valid range is 0.1% to 10%. Example: If Flow Switch Setpoint = 100 g/sec and Hysteresis = 5%, and the first measured flow rate is above 100 g/sec, the discrete output is OFF. It will remain OFF unless the flow rate drops below 95 g/sec. If this happens, the discrete output will turn ON, and remain ON until the flow rate rises above 105 g/sec. At this point it turns OFF and will remain OFF until the flow rate drops below 95 g/sec.

The setting of Discrete Output Fault Action is ignored. 6.5 Configure events An event occurs when the real-time value of a user-specified process variable moves past a user-defined setpoint. Events are used to provide notification of process changes or to perform specific transmitter actions if a process change occurs. Your transmitter supports two event models: 6.5.1 • Basic event model • Enhanced event model Configure a basic event Display Not available ProLink II ProLink > Configuration > Events ProLink III Device Tools > Configuration > Events > Basic Events Field Communicator Not available Overview A basic event is used to provide notification of process changes. A basic event occurs (is ON) if the real-time value of a user-specified process variable moves above (HI) or below (LO) a user-defined setpoint. You can define up to two basic events. Event status can be queried via digital communications, and a discrete output can be configured to report event status. Procedure 1. Select the event that you want to configure. 2.

You can define up to five enhanced events. For each enhanced event, you can assign one or more actions that the transmitter will perform if the enhanced event occurs. Procedure 1.

If this is not acceptable, wait until an appropriate time to assign actions to the event or discrete input. 6.6 Configure digital communications The digital communications parameters control how the transmitter will communicate using digital communications. Your transmitter supports the following types of digital communications: • HART/Bell 202 over the primary mA terminals • Modbus RTU via the service port Note The service port responds automatically to a wide range of connection requests. It is not configurable. 6.6.1 Configure HART/Bell 202 communications Display OFF-LINE MAINT > OFF-LINE CONFG > COMM ProLink II ProLink > Configuration > Device > Digital Comm Settings ProLink III Device Tools > Configuration > Communications > Communications (HART) Field Communicator Configure > Manual Setup > Inputs/Outputs > Communications > HART Communications Overview HART/Bell 202 communications parameters support HART communication with the transmitter's primary mA terminals over a HART/Bell 202 network. The HART/Bell 202 communications parameters include: • HART Address (Polling Address) Configuration and Use Manual 123 Integrate the meter with the control system • Loop Current Mode (ProLink II) or mA Output Action (ProLink III) • Burst Parameters (optional) • HART Variables (optional) Procedure 1. Set HART Address to a unique value on your network. Valid address values are between 0 and 15. The default address (0) is typically used unless you are in a multidrop environment. Tip Devices using HART protocol to communicate with the transmitter may use either HART Address or HART Tag (Software Tag) to identify the transmitter. Configure either or both, as required by your other HART devices. 2. Ensure Loop Current Mode (mA Output Action) is configured appropriately. Options Description Enabled The primary mA output reports process data as configured. Disabled The primary mA output is fixed at 4 mA and does not report process data. Important If you use ProLink II or ProLink III to set HART Address to 0, the program automatically enables Loop Current Mode. If you use ProLink II or ProLink III to set HART Address to any other value, the program automatically disables Loop Current Mode. This is designed to make it easier to configure the transmitter for legacy behavior. Always verify Loop Current Mode after setting HART Address. 3. (Optional) Enable and configure Burst Parameters. Tip In typical installations, burst mode is disabled. Enable burst mode only if another device on the network requires burst mode communication. 4. (Optional) Configure HART Variables.

Restriction Sensor simulation is available only on flowmeters with the enhanced core processor. Prerequisites Before enabling sensor simulation, ensure that your process can tolerate the effects of the simulated process values. Procedure 1. Navigate to the sensor simulation menu. Communications tool Menu path Display Not available ProLink II ProLink > Configuration > Sensor Simulation ProLink III Device Tools > Diagnostics > Testing > Sensor Simulation Field Communicator Service Tools > Simulate > Simulate Sensor 2. Enable sensor simulation. 3. For mass flow, set Wave Form as desired and enter the required values.

Observe the system response to the simulated values and make any appropriate changes to the transmitter configuration or to the system. 7. Modify the simulated values and repeat. 8. When you have finished testing or tuning, disable sensor simulation. Sensor simulation Sensor simulation allows you to test the system or tune the loop without having to create the test conditions in your process. When sensor simulation is enabled, the transmitter reports the simulated values for mass flow, density, and temperature, and takes all appropriate actions. For example, the transmitter might apply a cutoff, activate an event, or post an alarm. When sensor simulation is enabled, the simulated values are stored in the same memory locations used for process data from the sensor. The simulated values are then used throughout transmitter functioning. For example, sensor simulation will affect: 132 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Completing the configuration • All mass flow rate, temperature, and density values shown on the display or reported via outputs or digital communications • The mass total and mass inventory values • All volume calculations and data, including reported values, volume totals, and volume inventories • All mass, temperature, density, or volume values logged to Data Logger Sensor simulation does not affect any diagnostic values. Unlike actual mass flow rate and density values, the simulated values are not temperaturecompensated (adjusted for the effect of temperature on the sensor’s flow tubes). 7.2 Back up transmitter configuration ProLink II and ProLink III provide a configuration upload/download function which allows you to save configuration sets to your PC. This allows you to back up and restore your transmitter configuration. It is also a convenient way to replicate a configuration across multiple devices.

Regulatory agencies When installed, configured, and used as recommended by Micro Motion, the Weights & Measures application is certified by the following regulatory agencies: • NTEP (National Type Evaluation Program). NTEP requirements apply in the U.S.A. and Canada. • OIML (Organization of Legal Metrology). OIML requirements apply in all other world areas. Depending on the regulatory agency that governs your installation, different setup, configuration, and operation methods are applicable. Secured vs. unsecured When the Weights & Measures application is installed, the transmitter is always “secured” or “unsecured.” The transmitter leaves the factory in unsecured mode, with Status Alarm A027: Security Breach active. Additionally, flow measurement may be disabled. Measurement data from an unsecured transmitter cannot be used for custody transfer applications. To clear the alarm and enable flow measurement, you must configure the Weights & Measures application and secure the transmitter. When the transmitter is secured, the alarm is cleared and flow measurement is enabled automatically. Security types and requirements Before using the transmitter for Weights & Measures measurement, both metrological security and physical security must be implemented. Configuration and Use Manual 135 Set up the Weights & Measures application Metrological security Metrological security protects the transmitter from all changes that would affect measurement. This includes changes to configuration and some maintenance procedures. Micro Motion implements metrological security via “software security.” Software security is a setting inside the transmitter that programmatically disables the prohibited actions. Software security can be enabled or disabled from ProLink II and ProLink III. Practically speaking, software security provides complete protection against unauthorized changes or actions. Physical security Physical security is implemented by a seal installed by a certified Weights & Measures inspector. The seal prevents access to the service port terminals. Although the seal can be broken easily, it cannot be replaced by anybody other than a Weights & Measures inspector. This makes it easy to detect that security has been violated. If the seal is not intact, transmitter measurements are not valid for custody transfer. Configuration methods You must use ProLink II or ProLink III and a service port connection to configure the Weights & Measures parameters. 8.2 Set up the Weights & Measures application using ProLink II When your transmitter is set up to comply with OIML or NTEP requirements, and the transmitter is “secured,” selected measurement data from the transmitter is approved for Weights & Measures applications. Prerequisites Important Review the Weights & Measures requirements for your location and ensure that you are complying with all local requirements as well as the OIML or NTEP requirements. If necessary for your installation, arrange for a site visit by a certified Weights & Measures inspector, and ensure that the inspector is present for the appropriate portions of this procedure. Ensure that the transmitter is ready to be secured, i.e., it is configured as desired and you have performed all appropriate tests and adjustments. After the transmitter is secured, you cannot make any changes to configuration, many maintenance actions are disallowed, and some operator actions are disallowed. Procedure 136 1. Make a service port connection from ProLink II to your transmitter. 2. Navigate to the Weights & Measures menu: ProLink > Configuration > System. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Set up the Weights & Measures application 3. Set Approval to the appropriate regulatory agency for your application. 4. Set Totalizer Reset Options as desired. Option Description Not Resettable from Display and Digital Comm When the transmitter is secured, totalizers cannot be reset from either the transmitter display or digital communications. Resettable from Digital Comm Only When the transmitter is secured, you must use digital communications to reset the totalizers. Resettable from Display and Digital Comm When the transmitter is secured, you can use either the transmitter display or digital communications to reset the totalizers. Resettable from Display Only When the transmitter is secured, you must use the transmitter display to reset the totalizers. “Digital communications” refers to any method that uses Modbus or HART communications to interact with the transmitter. This includes ProLink II, ProLink III, the Field Communicator, and any host. 5.

Alarm Menu Password is required under German law for PTB-type approval for gas applications, and may be required in other locations or for other application types. 7. If required for your installation, read and record the firmware checksum values for the transmitter and the core processor: ProLink > Configuration > Device. The checksum values for the transmitter firmware and the core processor firmware must be read during meter commissioning to meet Weights & Measures requirements for gas applications in Germany. They may also be useful for MID/Welmec 7.2 test reports. 8. If required for your installation, configure Field Verification Zero (FVZ) as a display variable, then observe and record the current value of FVZ: ProLink > Configuration > Display. FVZ is a diagnostic variable that monitors the zero value over a period of 3 minutes. It must be read during meter commissioning to comply with MID requirements for Weights & Measures applications in Measuring Instrument Directive (MID) 2004/22/ EC. Refer to your Standard Operating Procedures documentation for detailed instructions. Configuration and Use Manual 137 Set up the Weights & Measures application 9. Enable software security: a. Choose Plug-ins > Enable/Disable Custody Transfer. b. Click Enable Custody Transfer. Important Depending on local requirements, this step may need to be witnessed by a certified Weights & Measures inspector. After this step, the transmitter is in a condition of metrological security (measurement security). The transmitter performs the following actions: • Securing all measurement parameters. You can read the current configurations but you cannot change them. • Clearing Status Alarm A027: Security Breach. 10. Install the physical seal. Important In most installations, the physical seal is a wire seal that must be installed by a certified Weights & Measures inspector. The seal is provided by the inspector. The physical seal is inserted through the locking clamps on the transmitter (if available on your transmitter). 8.3 Set up the Weights & Measures application using ProLink III When your transmitter is set up to comply with OIML or NTEP requirements, and the transmitter is “secured,” selected measurement data from the transmitter is approved for Weights & Measures applications.

You can use any other supported connection type. To read or obtain process data: - For an approved measurement, you must use an approved method. - If the measurement does not have to be approved, you can use any available method. Important The behavior of transmitter outputs and process variable values is modified by the Weights & Measures application. Ensure that you know the effects of this application on outputs and process variable values. • To reset totalizers: - If the transmitter is unsecured, you can reset totalizers. If you reset one totalizer, all other totalizers are reset automatically. - If the transmitter is secured, you may or may not be able to reset totalizers, depending on configuration. If totalizer reset is enabled, you cannot reset totalizers unless the flow rate is 0. To reset totalizers from the display, you may need to enter the alarm menu password, whether or not you have enabled it. The default value for Alarm Menu Password is 1234. Configuration and Use Manual 157 Operate the transmitter with the Weights & Measures application 10.1.1 • You cannot stop totalizers while the tranmitter is secured. • You cannot reset inventories while the transmitter is secured. Approved methods to read or obtain process data When the Weights & Measures application is installed, process data is approved for custody transfer use only if an approved method is used for reading or obtaining it. Note On the primary mA output, HART/Bell 202 communications may be used to poll for either temperature or pressure, in conjunction with process data reporting. 10.1.2 Large totalizer values on the display (OIML applications only) If Approval is set to OIML and totalizer values become large enough, the display handles large values in a special way. The value displayed may not reflect the actual value. The display is able to show a maximum of eight characters, including the decimal point. For all totalizer values configured as display variables, the position of the decimal point on the display is fixed to the configured precision of the display variable. When the totalizer reaches the largest value that can be displayed in these circumstances: • The digits roll over. • The decimal point does not move. • The number of digits on the display does not change. • The internal totalizer is reset to 0. For example, the value 99999.999 rolls over to 00000.000. Tip If you are not sure whether or not the totalizer value on the display has rolled over, check the value by using another method to read the current data. Notes 158 • The mass and volume totalizers do not necessarily roll over at the same time. • This feature does not apply to inventories. The display presents large inventory values in the standard manner.

If the transmitter is in secured mode, switch to unsecured mode. 2. Take any required actions related to the cause of the security breach. 3. Switch to secured mode. Replacing the core processor in a Weights & Measures installation In a Weights & Measures installation, replacing the core processor requires re-sealing the transmitter. When the transmitter is first secured, the core processor’s unique ID is registered with the transmitter. If you replace the core processor with another core processor, the transmitter will post Status Alarm A026: Sensor/Xmtr Communication Error. To clear this alarm, you must switch the transmitter to unsecured mode and resecure it. This requires breaking the physical seal and reinstalling it when the entire process is complete. Other procedures may be required. Refer to the Weights & Measurements documentation for your installation. Important In most cases, the physical seal must be installed by a certified Weights & Measures inspector. 164 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Measurement support 11 Measurement support Topics covered in this chapter: • • • • • • • 11.1 Options for measurement support Use Smart Meter Verification Zero the flowmeter Validate the meter Perform a (standard) D1 and D2 density calibration Perform a D3 and D4 density calibration (T-Series sensors only) Perform temperature calibration Options for measurement support Micro Motion provides several measurement support procedures to help you evaluate and maintain your flowmeter's accuracy. The following methods are available: • Smart Meter Verification evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or force divided by displacement. Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance. • Meter validation compares flowmeter measurements reported by the transmitter to an external measurement standard. Meter validation requires one data point. • Calibration establishes the relationship between a process variable and the signal produced at the sensor. You can calibrate the flowmeter for zero, density, and temperature. Density and temperature calibration require two data points (low and high) and an external measurement for each. Tips 11.2 • Perform Smart Meter Verification at regular intervals to get the best data on your meter's performance. • To prove the meter against a regulatory standard, or to correct measurement error, use meter validation and meter factors. • Before performing a field calibration, contact Micro Motion to see if there is an alternative. In many cases, field calibrations have a negative effect on measurement accuracy. Use Smart Meter Verification You can run a Smart Meter Verification test, view and interpret the results, and set up automatic execution. Configuration and Use Manual 165 Measurement support 11.2.1 Smart Meter Verification requirements To use Smart Meter Verification, the transmitter must be paired with an enhanced core processor, and the Smart Meter Verification option must be ordered for the transmitter. See Table 11-1 for the minimum version of the transmitter, enhanced core processor, and communication tool needed to support Smart Meter Verification. (If you are going to perform Smart Meter Verification using the display, only the transmitter and enhanced core processor versions apply.) Table 11-1: Minimum version to support Smart Meter Verification Item Minimum version Transmitter 6.0 Enhanced core processor 3.6 ProLink II 2.9 ProLink III 1.0 Field Communicator HART device description: device rev 6, DD rev 2 If your devices or tools do not meet the minimum version requirements for Smart Meter Verification, you still may have access to an older version of meter verification if the option was ordered for your transmitter. See Table 11-2 for a description of the major differences between the older meter verification and the newer Smart Meter Verification. Table 11-2: Major differences between meter verification and Smart Meter Verification 11.2.2 Feature Meter verification (older) Smart Meter Verification (newer) Measurement interruption Suspended during the test (3 minutes) No interruption necessary Result storage No results stored in the transmitter Last 20 results stored in the transmitter Results reporting Pass/fail/abort Pass/fail/abort, abort code, comparison tables and graphs for stored test results(1) Test start methods Manual only Manual, scheduled, event-based Smart Meter Verification test preparation Although it is not necessary to match factory conditions or change the transmitter's configuration during a Smart Meter Verification test, the test will run more smoothly when conditions are stable. (1) Detailed test analyses such as comparison graphs are not available on the local display. 166 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Measurement support Smart Meter Verification has an output mode called Continuous Measurement that allows the transmitter to keep measuring while the test is in progress. If you choose to run the test in Last Measured Value or Fault modes instead, the transmitter outputs will be held constant for the two minute duration of the test. If control loops depend on transmitter outputs, take appropriate action. Avoid process instability during the test. If conditions are too unstable, the Smart Meter Verification test will abort. To maximize process stability: • Maintain a constant fluid pressure and temperature. • Avoid changes to fluid composition, e.g., two-phase flow or settling. • Maintain a constant flow rate. Tips 11.2.3 • The Smart Meter Verification test runs best when flow is stopped through the sensor. • Smart Meter Verification is not affected by any configured transmitter parameters for flow, density, or temperature.

In other words, the stiffness of the left and right pickoffs match the factory values plus or minus the specification uncertain limit. If transmitter zero and configuration match factory values, the sensor will meet factory specifications for flow and density measurement. It is expected that meters will pass meter verification every time the test is run. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Measurement support Fail The test result is not within the specification uncertainty limit. Micro Motion recommends that you immediately repeat the meter verification test. If during the failed test you had set outputs to Continue Measurement, set outputs to Fault or Last Measured Value instead. • If the meter passes the second test, the first result can be ignored. • If the meter fails the second test, the flow tubes may be damaged. Use your process knowledge to determine the possibilities for damage and the appropriate actions for each. These actions might include removing the meter from service and physically inspecting the tubes. At minimum, you should perform a flow validation and a density calibration. Abort A problem occurred with the meter verification test (e.g., process instability) or you stopped the test manually. See Table 11-3 for a list of abort codes, a descript of each code, and possible actions you can take in response. Table 11-3: Smart Meter Verification abort codes 11.2.5 Code Description Recommended actions 1 User-initiated abort None required. Wait 15 seconds before starting another test. 3 Frequency drift Ensure that temperature, flow, and density are stable, and rerun the test. 5 High drive gain Ensure that flow is stable, minimize entrained gas, and rerun the test. 8 Unstable flow Check factors that could cause process instability, then rerun the test. To maximize process stability: • Maintain a constant fluid pressure and temperature. • Avoid changes to fluid composition, e.g., two-phase flow or settling. • Maintain a constant flow rate. 13 No factory reference data for meter verification test performed on air Contact Micro Motion. 14 No factory reference data for meter verification test performed on water Contact Micro Motion. 15 No configuration data for meter verification Contact Micro Motion.

If the transmitter value for mass flow, volume flow, or density measurement is significantly different from the external measurement standard, you may want to adjust the corresponding meter factor. The flowmeter’s actual measurement is multiplied by the meter factor, and the resulting value is reported and used in further processing. Prerequisites Identify the meter factor(s) that you will calculate and set. You may set any combination of the three meter factors: mass flow, volume flow, and density. Note that all three meter factors are independent: • The meter factor for mass flow affects only the value reported for mass flow. • The meter factor for density affects only the value reported for density. • The meter factor for volume flow affects only the value reported for volume flow or gas standard volume flow. Important To adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for mass flow and a meter factor for density will not produce the desired result. The volume flow calculations are based on original mass flow and density values, before the corresponding meter factors have been applied. If you plan to calculate the meter factor for volume flow, be aware that validating volume in the field may be expensive, and the procedure may be hazardous for some process fluids. Therefore, because volume is inversely proportional to density, an alternative to direct measurement is to calculate the meter factor for volume flow from the meter factor for density. See Section 11.4.1 for instructions on this method. Obtain a reference device (external measurement device) for the appropriate process variable. Important For good results, the reference device must be highly accurate. 184 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Measurement support Procedure 1. Determine the meter factor as follows: a. Use the flowmeter to take a sample measurement. b. Measure the same sample using the reference device. c. Calculate the meter factor using the following formula: ReferenceMeasurement NewMeterFactor = ConfiguredMeterFactor x FlowmeterMeasurement 2. Ensure that the calculated meter factor is between 0.8 and 1.2, inclusive. If the meter factor is outside these limits, contact Micro Motion customer service. 3. Configure the meter factor in the transmitter. Example: Calculating the meter factor for mass flow The flowmeter is installed and validated for the first time. The mass flow measurement from the transmitter is 250.27 lb. The mass flow measurement from the reference device is 250 lb. The mass flow meter factor is calculated as follows: MeterFactorMassFlow = 1 x 250 250.27 = 0.9989 The first meter factor for mass flow is 0.9989. One year later, the flowmeter is validated again. The mass flow measurement from the transmitter is 250.07 lb. The mass flow measurement from the reference device is 250.25 lb. The new mass flow meter factor is calculated as follows: MeterFactorMassFlow = 0.9989 x 250.25 250.07 = 0.9996 The new meter factor for mass flow is 0.9996. 11.4.1 Alternate method for calculating the meter factor for volume flow The alternate method for calculating the meter factor for volume flow is used to avoid the difficulties that may be associated with the standard method. This alternate method is based on the fact that volume is inversely proportional to density. It provides partial correction of the volume flow measurement by adjusting for the portion of the total offset that is caused by the density measurement offset. Use this method only when a volume flow reference is not available, but a density reference is available. Procedure 1. Calculate the meter factor for density, using the standard method (see Section 11.4). 2. Calculate the meter factor for volume flow from the meter factor for density: Configuration and Use Manual 185 Measurement support MeterFactorVolume = 1 MeterFactorDensity Note The following equation is mathematically equivalent to the first equation. You may use whichever version you prefer. MeterFactorVolume = ConfiguredMeterFactorDensity 11.5 x DensityFlowmeter DensityReferenceDevice 3. Ensure that the calculated meter factor is between 0.8 and 1.2, inclusive. If the meter factor is outside these limits, contact Micro Motion customer service. 4. Configure the meter factor for volume flow in the transmitter. Perform a (standard) D1 and D2 density calibration Density calibration establishes the relationship between the density of the calibration fluids and the signal produced at the sensor. Density calibration includes the calibration of the D1 (low-density) and D2 (high-density) calibration points. Important Micro Motion flowmeters are calibrated at the factory, and normally do not need to be calibrated in the field. Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact Micro Motion before calibrating the flowmeter. Tip Micro Motion recommends using meter validation and meter factors, rather than calibration, to prove the meter against a regulatory standard or to correct measurement error. 11.5.1 Perform a D1 and D2 density calibration using ProLink II Prerequisites 186 • During density calibration, the sensor must be completely filled with the calibration fluid, and flow through the sensor must be at the lowest rate allowed by your application.

Use sensor simulation for troubleshooting When sensor simulation is enabled, the transmitter reports user-specified values for mass flow, temperature, and density. This allows you to reproduce various process conditions or to test the system. You can use sensor simulation to help distinguish between legitimate process noise and externally caused variation. For example, consider a receiving device that reports an unexpectedly erratic flow value. If sensor simulation is enabled and the observed flow rate does not match the simulated value, the source of the problem is likely to be somewhere between the transmitter and the receiving device. 218 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Troubleshooting Important When sensor simulation is active, the simulated value is used in all transmitter outputs and calculations, including totals and inventories, volume flow calculations, and concentration calculations. Disable all automatic functions related to the transmitter outputs and place the loop in manual operation. Do not enable simulation mode unless your application can tolerate these effects, and be sure to disable simulation mode when you have finished testing. For more information on using sensor simulation using ProLink II, see Section 7.1. 12.9 Check power supply wiring If the power supply wiring is damaged or improperly connected, the transmitter may not receive enough power to operate properly. Prerequisites You will need the installation manual for your transmitter. Procedure 1. Before inspecting the power supply wiring, disconnect the power source. CAUTION! If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. 2. Verify that the correct external fuse is used. An incorrect fuse can limit current to the transmitter and keep it from initializing. 3. Ensure that the power supply wires are connected to the correct terminals. 4. Verify that the power supply wires are making good contact, and are not clamped to the wire insulation. 5. Inspect the voltage label on the inside of the field-wiring compartment. The voltage supplied to the transmitter should match the voltage specified on the label. 6. Reapply power to the transmitter. CAUTION! If the transmitter is in a hazardous area, do not reapply power to the transmitter with the housing cover removed. Reapplying power to the transmitter while the housing cover is removed could cause an explosion. 7. Use a voltmeter to test the voltage at the transmitter’s power supply terminals. The voltage should be within specified limits. For DC power, you may need to size the cable. Configuration and Use Manual 219 Troubleshooting 12.10 Check sensor-to-transmitter wiring A number of power-supply and output problems may occur if the wiring between the sensor and the transmitter is improperly connected, or if the wiring becomes damaged. Prerequisites You will need the installation manual for your transmitter. Procedure 1. Before opening the wiring compartments, disconnect the power source. CAUTION! If the transmitter is in a hazardous area, wait five minutes after disconnecting the power. 12.11 2. Verify that the transmitter is connected to the sensor according to the information provided in your transmitter installation manual. 3. Verify that the wires are making good contact with the terminals. 4. Check the continuity of all wires from the transmitter to the sensor. Check grounding The sensor and the transmitter must be grounded. If the core processor is installed as part of the transmitter or the sensor, it is grounded automatically. If the core processor is installed separately, it must be grounded separately. Prerequisites You will need: • Installation manual for your sensor • Installation manual for your transmitter Procedure Refer to the sensor and transmitter installation manuals for grounding requirements and instructions. 12.12 Perform loop tests A loop test is a way to verify that the transmitter and the remote device are communicating properly.

However, Micro Motion recommends performing a loop test for every input or output available on your transmitter. The inputs and outputs available on your transmitter vary according to your purchase option and your channel configuration. You may not need to perform all of the loop tests described here. Prerequisites Before performing a loop test, configure the channels for the transmitter inputs and outputs that will be used in your application. Follow appropriate procedures to ensure that loop testing will not interfere with existing measurement and control loops. Procedure 1. Test the mA output(s). a.

Postrequisites 12.13 • If the mA output reading was slightly off at the receiving device, you can correct this discrepancy by trimming the output. • If the mA output reading was significantly off (±200 microamps), or if at any step the reading was faulty, verify the wiring between the transmitter and the remote device, and try again. • If the discrete output reading is reversed, check the setting of Discrete Output Polarity. Check for radio frequency interference (RFI) The transmitter's frequency output or discrete output can be affected by radio frequency interference (RFI). Possible sources of RFI include a source of radio emissions, or a large transformer, pump, or motor that can generate a strong electromagnetic field. Several methods to reduce RFI are available. Use one or more of the following suggestions, as appropriate to your installation. Procedure • 226 Eliminate the RFI source. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Troubleshooting 12.14 • Move the transmitter. • Use shielded cable for the frequency output or discrete output. - Terminate the shielding at the output device. If this is impossible, terminate the shielding at the cable gland or conduit fitting. - Do not terminate the shielding inside the wiring compartment. - 360-degree termination of shielding is unnecessary. Check the HART communication loop If you cannot establish or maintain HART communications, the HART loop may be wired incorrectly. Prerequisites You will need: • A copy of your transmitter installation manual • A Field Communicator • Optional: the HART Application Guide, available at www.hartcomm.org Procedure 1. Verify that the loop wires are connected as shown in the wiring diagrams in the transmitter installation manual. If your HART network is more complex than the wiring diagrams in the transmitter installation manual, contact either Micro Motion or the HART Communication Foundation. 2. Disconnect the primary mA output wiring from the transmitter. 3. Install a 250–1000 Ω resistor across the transmitter’s primary mA output terminals. 4. Check the voltage drop across the resistor (4–20 mA = 1–5 VDC). If voltage drop is less than 1 VDC, add resistance to achieve a voltage drop of greater than 1 VDC. 5. Connect a Field Communicator directly across the resistor and attempt to communicate (poll). If communication with the transmitter cannot be established, the transmitter may need service. Contact Micro Motion. 12.15 Check HART Address and Loop Current Mode If the transmitter is producing a fixed current from the mA output, the Loop Current Mode parameter may be disabled. Configuration and Use Manual 227 Troubleshooting When Loop Current Mode is disabled, the mA output produces a fixed value, and does not report process data or implement its fault action. When HART Address is changed, some configuration tools will automatically change Loop Current Mode. Tip Always verify Loop Current Mode after setting or changing HART Address. Procedure 1. Set HART Address as appropriate for your HART network. The default address is 0. This is the recommended value unless the transmitter is in a multidrop network. 2. 12.16 Set Loop Current Mode to Enabled. Check HART burst mode HART burst mode can cause the transmitter to output unexpected values. Burst mode is normally disabled, and should only be enabled if another device on the HART network requires burst mode communication. 12.17 1. Check to see if burst mode is enabled or disabled. 2. If burst mode is enabled, disable it. Check the trimming of the mA output If the trim values for the mA output are inaccurate, the transmitter will under-compensate or over-compensate the output. 12.18 1. Trim the output, following the standard procedure. 2. If this does not correct the problem, contact Micro Motion. Check Lower Range Value and Upper Range Value If the process conditions fall below the configured Lower Range Value (LRV) or rise above the configured Upper Range Value (URV), the transmitter outputs may send unexpected values. 228 1. Make a note of your current process conditions. 2. Check the configuration of the LRV and URV. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Troubleshooting 12.19 Check mA Output Fault Action mA Output Fault Action controls the behavior of the mA output if the transmitter encounters an internal fault condition. If the mA output is reporting a constant value below 4 mA or above 20 mA, the transmitter may be in a fault condition. 1. Check the status alarms for active fault conditons. 2. If there are active fault conditions, the transmitter is performing correctly. If you want to change its behavior, consider the following options: • Change the setting of mA Output Fault Action. • For the relevant status alarms, change the setting of Alarm Severity to Ignore. 3. 12.20 If there are no active fault conditions, continue troubleshooting. Check Frequency Output Maximum Pulse Width If Frequency Output Maximum Pulse Width is set incorrectly, the frequency output may report an incorrect value. Verify the configuration of Frequency Output Maximum Pulse Width. For most applications, the default value for Frequency Output Maximum Pulse Width is appropriate. This corresponds to a 50% duty cycle. 12.21 Check Frequency Output Scaling Method If Frequency Output Scaling Method is set incorrectly, the frequency output may report an incorrect value. 12.22 1. Verify the configuration of Frequency Output Scaling Method. 2. If you changed the setting of Frequency Output Scaling Method, check the settings of all other frequency output parameters. Check Frequency Output Fault Action The Frequency Output Fault Action controls the behavior of the frequency output if the transmitter encounters an internal fault condition. If the frequency output is reporting a constant value, the transmitter may be in a fault condition. 1. Check the status alarms for active fault conditons. 2. If there are active fault conditions, the transmitter is performing correctly. If you want to change its behavior, consider the following options: • Change the setting of Frequency Output Fault Action. Configuration and Use Manual 229 Troubleshooting • For the relevant status alarms, change the setting of Alarm Severity to Ignore. 3. 12.23 If there are no active fault conditions, continue troubleshooting. Check Flow Direction If Flow Direction is set inappropriately for your process, the transmitter may report unexpected flow values or totals. The Flow Direction parameter interacts with actual flow direction to affect flow values, flow totals and inventories, and output behavior. For the simplest operation, actual process flow should match the flow arrow that is on the side of the sensor case. Procedure 12.24 1. Verify the actual direction of process flow through the sensor. 2. Verify the configuration of Flow Direction. Check the cutoffs If the transmitter cutoffs are configured incorrectly, the transmitter may report zero flow when flow is present, or very small amounts of flow under no-flow conditions. There are separate cutoff parameters for mass flow rate, volume flow rate, gas standard volume flow rate (if applicable), and density. There is an independent cutoff for each mA output on your transmitter. The interaction between cutoffs sometimes produces unexpected results. Procedure Verify the configuration of the cutoffs. Tip For typical applications, Micro Motion recommends setting Mass Flow Cutoff to the zero stability value for your sensor, multiplied by 10. Zero stabiliy values can be found in the Product Data Sheet for your sensor. 12.25 Check for slug flow (two-phase flow) Slug flow (two-phase flow, entrained gas) can cause spikes in the drive gain. This may cause the transmitter to report zero flow, or to post several different alarms. 1. Check for slug flow alarms. If the transmitter is not generating slug flow alarms, slug flow is not the source of your problem. 2. 230 Check the process for cavitation, flashing, or leaks. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Troubleshooting 3. Monitor the density of your process fluid output under normal process conditions. 4. Check the settings of Slug Low Limit, Slug High Limit, and Slug Duration. Tip You can reduce the occurrence of slug flow alarms by setting Slug Low Limit to a lower value, Slug High Limit to a higher value, or Slug Duration to a higher value. 12.26 Check the drive gain Excessive or erratic drive gain may indicate any of a variety of process conditions, sensor problems, or configuration problems. To know whether your drive gain is excessive or erratic, you must collect drive gain data during the problem condition and compare it to drive gain data from a period of normal operation. Excessive (saturated) drive gain Table 12-8: Possible causes and recommended actions for excessive (saturated) drive gain Possible cause Recommended actions Slug flow Check for slug flow. See Section 12.25. Partially filled flow tube Correct process conditions so that the flow tubes are full. Plugged flow tube Check the pickoff voltages (see Section 12.27).

Observe and record drive gain data over an appropriate period of time, under a variety of process conditions. Check the pickoff voltage If the pickoff voltage readings are unusually low, you may have any of a variety of process or equipment problems. To know whether your pickoff voltage is unusually low, you must collect pickoff voltage data during the problem condition and compare it to pickoff voltage data from a period of normal operation. 232 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Troubleshooting Table 12-10: Possible causes and recommended actions for low pickoff voltage 12.27.1 Possible cause Recommended actions Air entrainment • Increase the inlet or back pressure at the sensor. • If a pump is located upstream from the sensor, increase the distance between the pump and sensor. • The sensor may need to be reoriented.

Contact Micro Motion for more information. There should be no open circuits, that is, no infinite resistance readings. The left pickoff and right pickoff readings should be the same or very close (±5 Ω). If there are any unusual readings, repeat the coil resistance tests at the sensor junction box to eliminate the possibility of faulty cable. The readings for each coil pair should match at both ends. 5. Test the terminals in the sensor junction box for shorts to case. a. Leave the terminal blocks disconnected. b. Remove the lid of the junction box. c. Testing one terminal at a time, place a DMM lead on the terminal and the other lead on the sensor case. With the DMM set to its highest range, there should be infinite resistance on each lead. If there is any resistance at all, there is a short to case. 6.

ProLink II requirements To install ProLink II, you must have: • The ProLink II installation media • The ProLink II installation kit for your connection type To obtain ProLink II and the appropriate installation kit, contact Micro Motion. ProLink II documentation Most of the instructions in this manual assume that you are already familiar with ProLink II or that you have a general familiarity with Windows programs. If you need more information than this manual provides, see the ProLink II manual (ProLink® II Software for Micro Motion® Transmitters: Installation and Use Manual). In most ProLink II installations, the manual is installed with the ProLink II program. Additionally, the ProLink II manual is available on the Micro Motion documentation CD or the Micro Motion web site (www.micromotion.com). ProLink II features and functions ProLink II offers complete transmitter configuration and operation functions. ProLink II also offers a number of additional features and functions, including: • The ability to save the transmitter configuration set to a file on the PC, and reload it or propagate it to other transmitters • The ability to log specific types of data to a file on the PC • A commissioning wizard • A proving wizard • A gas wizard These features are documented in the ProLink II manual. They are not documented in the current manual. Configuration and Use Manual 263 Using ProLink II with the transmitter ProLink II messages As you use ProLink II with a Micro Motion transmitter, you will see a number of messages and notes. This manual does not document all of these messages and notes. Important The user is responsible for responding to messages and notes and complying with all safety messages. B.2 Connect with ProLink II A connection from ProLink II to your transmitter allows you to read process data, configure the transmitter, and perform maintenance and troubleshooting tasks. B.2.1 ProLink II connection types Different connection types are available for connecting from ProLink II to the transmitter. Choose the connection type appropriate to your network and the tasks you intend to perform. The transmitter supports the following ProLink II connection types: • Service port connections • HART/Bell 202 connections When selecting a connection type, consider the following: 264 • Service port connections use standard connection parameters that are already defined in ProLink II, and therefore you do not have to configure them. • HART/Bell 202 connections use standard HART connection parameters that are already defined in ProLink II. The only parameter you must configure is the transmitter address. • Some connection types require opening the wiring compartment or the power supply compartment. These connection types should be used only for temporary connections, and may require extra safety precautions. • Modbus connections, including service port connections, are typically faster than HART connections. • When you are using a HART connection, ProLink II will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed. • You cannot make concurrent connections if the connections use the same terminals. You can make concurrent connections if the connections use different terminals. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Using ProLink II with the transmitter B.2.2 Make a service port connection CAUTION! If the transmitter is in a hazardous area, do not use a service port connection. Service port connections require opening the wiring compartment, and opening the wiring compartment while the transmitter is powered up could cause an explosion. To connect to the transmitter in a hazardous environment, use a connection method that does not require removing the transmitter housing cover. Prerequisites • ProLink II installed and licensed on your PC • One of the following: - RS-232 to RS-485 signal converter - USB to RS-485 signal converter • An available serial port or USB port • Adapters as required (for example, 9-pin to 25-pin) Procedure 1. Attach the signal converter to the serial port or USB port on your PC. 2. Access the service port terminals: a. Remove the transmitter end-cap to access the wiring compartment. b. Loosen the screw on the Warning flap and open the power supply compartment. 3. Connect the leads from the signal converter to the service port, terminals 7 (RS-485/ A) and 8 (RS-485/B).

Set the COM Port value to the PC COM port that you are using for this connection. 8. Click Connect. Need help? If an error message appears: • Switch the leads and try again. • Ensure that you have specified the correct COM port. • Check the physical connection between the PC and the transmitter. B.2.3 Make a HART/Bell 202 connection You can connect directly to the primary mA terminals on the transmitter, to any point in a local HART loop, or to any point in a HART multidrop network. 266 Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Using ProLink II with the transmitter CAUTION! If the transmitter is in a hazardous area, do not connect directly to the transmitter terminals. Connecting directly to the transmitter terminals requires opening the wiring compartment, and opening the wiring compartment while the transmitter is powered up could cause an explosion. To connect to the transmitter in a hazardous environment, use a connection method that does not require opening the wiring compartment. CAUTION! If you connect directly to the mA terminals, the transmitter's mA output may be affected. If you are using the mA output for flow control, set devices for manual control before connecting directly to the mA terminals. Prerequisites • ProLink II installed and licensed on your PC • One of the following: - RS-232 to Bell 202 signal converter - USB to Bell 202 signal converter • An available serial port or USB port • Adapters as required (for example, 9-pin to 25-pin) Procedure 1. Attach the signal converter to the serial port or USB port on your PC. 2. To connect directly to the transmitter terminals: a. Remove the transmitter end-cap to access the wiring compartment. b. Connect the leads from the signal converter to terminals 1 and 2. Tip HART connections are not polarity-sensitive. It does not matter which lead you attach to which terminal. c.

C.2 Connect with ProLink III A connection from ProLink III to your transmitter allows you to read process data, configure the transmitter, and perform maintenance and troubleshooting tasks. C.2.1 ProLink III connection types Different connection types are available for connecting from ProLink III to the transmitter. Choose the connection type appropriate to your network and the tasks you intend to perform. The transmitter supports the following ProLink III connection types: • Service port connections • HART/Bell 202 connections When selecting a connection type, consider the following: 284 • Service port connections use standard connection parameters that are already defined in ProLink III, and therefore you do not have to configure them. • HART/Bell 202 connections use standard HART connection parameters that are already defined in ProLink III. The only parameter you must configure is the transmitter address. • Some connection types require opening the wiring compartment or the power supply compartment. These connection types should be used only for temporary connections, and may require extra safety precautions. • Modbus connections, including service port connections, are typically faster than HART connections. • When you are using a HART connection, ProLink III will not allow you to open more than one window at a time. This is done to manage network traffic and optimize speed. • You cannot make concurrent connections if the connections use the same terminals. You can make concurrent connections if the connections use different terminals. Micro Motion® Model 2700 Transmitters with Intrinsically Safe Outputs Using ProLink III with the transmitter C.2.2 Make a service port connection CAUTION! If the transmitter is in a hazardous area, do not use a service port connection.

You do not need to install the transmitter separately, but you will need to connect power supply and I/O wiring. Figure F-1: Integral installation Transmitter Sensor • High-temperature flexible conduit – Some high-temperature meters come preinstalled with a flexible conduit between the sensor and the transmitter. You do not have to connect any wires between the transmitter and the sensor, but you do need to mount the electronics separately and connect power and I/O wiring to the transmitter. Configuration and Use Manual 329 Transmitter components and installation wiring Figure F-2: High-temperature flexible conduit installation High-temperature flexible conduit installations use the same installation instructions as 4-wire remote installations, except that the distance between the sensor and the electronics is limited by the length of the flexible conduit. • 4-wire remote – The transmitter is installed remotely from the sensor. You need to mount the transmitter separately from the sensor, connect a 4-wire cable between the transmitter and sensor, and connect power and I/O wiring to the transmitter.

You need to mount the transmitter/core processor assembly separately from the sensor, connect a 9-wire cable between the transmitter/core processor, and connect power and I/O wiring to the transmitter. Configuration and Use Manual 331 Transmitter components and installation wiring Figure F-5: 9-wire remote installation type Transmitter Junction box 9-wire cable Sensor • 332 Remote core processor with remote sensor – A remote core process with remote sensor installation separates all three components – transmitter, core processor, and sensor – all of which are installed separately. A 4-wire cable connects the transmitter to the core processor, and a 9-wire cable connects the core processor to the sensor.
